To all whom it may concern:

Be it known. that 1, JOHN Rnnwrcn, a citizenYlof the United States, residing at Emmett, in the county of Gem and State of Idaho, have invented new and useful. Improvements in Automohile-VVheels, of which the following is a specification.

This inventionrelates to improvements in wheels for automobiles and other vehicles 55 inner side of the wheel and especially with'reference to the provision of a wheel of this type embodying a demountablc rim the object of the invention being to efi'ect improvements in the constructionof the wheel and of the demountable rim whereby the demountable rim may be readily mounted and locked in such position and may be also readily demoun-ted when desired and without the employment of tools of any kind.

With the above and other objects in'view the invention consists in the construction, combination and arran ement of devices hereinafter described and claimed.

In the accompanying drawings Figure l is an elevation of a wheel ,provided with a demountahle rim and a locking ring for the demountahle rim constructed and arranged in accordance with. my invention.

. Fig. 2 is a similar view showing the opposite side of the wheel.

Fig. 3 is a sectional view of the same on the plane indicated by the line 33 of F1 l.

ig. 4 is a detailed perspective view of the demountahle rim.

Fig.6 is a similar view of the wheel and the locking ring.

The wheel 1 is provided with the usual telly or rim 2 which in accordance with my invention is provided at suitable points with peripheral notches 3 which extend across the same transversely and the sides of which converge toward the inner side of the wheel. These notches are preferably arranged equally distant apart. the telly of the wheel is a locking ring 4 which is provided with notches 5 which correspond with the notehes 3, segmental locking portions 6 being formed between said notches 5. The locking ring is also provided with segmental slots 7 which are concentric therewith and with the wheel. Bolts 8 secure the locking ring sl-idalily to the rim and extend 0n the inner side of application filed July 13, 1917. $eria1 No. 180,434.

fipeciflcation pf Letters rattan, P me M 2%19 1'3:

through the slots 7 and hence permit the qllf locking ring to be partially turned in. either v direction to arrange its notches 5 either or out of registry with the notches 3.

The demountable rim 9, which may otherwise be of any suitable construction and may he provided with any suitable form of tire, is provided on'its inner eriphery or side with transversely arrange segments 10 the sides of which converge in one direction, so that said segments are substantially wedgeshape, and the said segmentsare adapted to enter the notches of the telly and locking ring when the locking ring is arranged with its notches in registry with the notches of the felly. Owing to the wedge-shape of the segments further movement of the demountable nm is arrested when the demountable rim is arranged on the wheel rim in the re qu ired relation thereto. The said segments 10 are each provided with a groove 11 to receive one of the flanges 6 of the locking ring when the latter is turned to locking position with its notches out of registrywith the notches of the folly and the wedge-shaped locking segments of the demountable rim. r

The usual valve for inflating the tire is indicated at 12. When demounting the demountable rim the locking ring is first turned to releasing position to arrange its notches in registry with the notches of the folly and disengage its segment flanges from the grooves of the locking segments of the demountable rim and said demountable rim is then grasped at a point opposite the valve and drawn outwardly from the correspond;

ing portion of the wheel and may then be readily disengaged from the valve, without disturbing the latter, the opening in the felly and through which the valve extends being suiiiciently large to clear the valve when the demouutable rim is thus manipulated.

To secure the locking ring in lockin position a thumb screw 13 is provided w ich is engaged in a threaded opening in the wheel rim and arranged in one end of one of the slots of the locking ring.

. While T have herein shown and described a preferred form of my invention I would have it understood that changes may be made in the form, proportion and construction of the several parts, without departing from the spirit of my invention-and within the scope of the appended claim.

Having thus described my invention, What its inner side for arrangement in the notches 10 I claim is m? the felly, said segments having grooves IILCOlllbiflatlOll with a Wheel having a for engagement by the locking ring, the said fully provided with peripheral notches and segments being Wedge-shape and the sides -5 a locking ring mounted for oscillatory of said notches being eorrespoi'idingly angulnovelnenl. on one side of the felly an l-havlarly related to enable said locking seg- 15 'ing notches adapted to he arranged in or out ments to fit therein.
